| IfcModulusOfTranslationalSubgradeReactionSelect | ADDED |
A measure for modulus of translational subgrade reaction which expresses the translational bedding of a structural curve item per length. TRUE denotes infinite stiffness (rigidity). FALSE denotes no stiffness (a release). A numeric value denotes finite linear-elastic stiffness.
